Research of the Day
Adolescent Vaping Cessation: Randomized Trial of Behavioral Interventions
This RCT compared three vaping cessation approaches in 1,200 adolescents: text-based support, in-person counseling, and combined intervention. Combined approach showed highest quit rates at 6-month follow-up.
Key findings: (1) 28% quit rate with combined intervention vs 15% text-only; (2) Nicotine dependence level predicted quit success; (3) Most adolescents wanted to quit but lacked support resources.
Screen for vaping at every adolescent visit. Offer cessation resources proactively—most teens want to quit. Combine counseling with digital support for best outcomes.
Popular Beliefs
Shaving makes hair grow back thicker and darker
What the evidence shows: Shaving removes hair at the skin surface, leaving a blunt tip that may feel coarser as it grows out. However, it does not affect hair thickness, color, or growth rate. This is an optical illusion from the blunt vs. tapered hair shaft.
Letting babies walk early causes bowlegs
What the evidence shows: There is no evidence that early walking causes bowlegs. Most infants have some degree of bowing that typically resolves by age 3-4. Pathologic bowing has other causes (Blount disease, rickets). Encourage normal motor development and monitor for asymmetric or progressive bowing.
Wait 30 minutes after eating before swimming
What the evidence shows: There's no evidence that swimming after eating causes cramps or drowning. While digestion diverts some blood flow to the gut, it doesn't impair swimming ability in normal circumstances. Common-sense supervision is always important regardless of meal timing.
Behaviors
Breakfast Consumption and Cognitive Performance in School-Age Children
This crossover study compared cognitive test performance in 200 children ages 8-11 on days with and without breakfast. Skipping breakfast significantly impaired attention, memory, and problem-solving speed, with effects noticeable by mid-morning.
Key findings: (1) 18% slower response time on attention tasks without breakfast; (2) Short-term memory scores 12% lower; (3) Nutrient-dense breakfasts outperformed high-sugar options for sustained attention.
Screen for breakfast skipping during well visits, especially in lower-income families. Connect families with school breakfast programs when appropriate. Quick, balanced breakfast options can be discussed as anticipatory guidance.
Genetics
Genetic Predictors of Peanut Allergy Persistence
Genome-wide association study identifies genetic variants associated with peanut allergy persistence versus resolution. Children with certain variants are more likely to outgrow their allergy, informing timing of oral food challenges.
Key findings: (1) 4 genetic variants strongly associated with persistence; (2) Genetic testing could reduce unnecessary avoidance and challenges; (3) Environmental factors remain important in allergy development.
Genetic testing may soon help predict which children will outgrow allergies. For now, continue regular reassessment with IgE testing and oral challenges as clinically indicated.
